Rapper Nick releases SA poll commercial

South Australia's master of political stunts Nick Xenophon has struck again, this time with a "so bad it's good" TV commercial where he raps about the state's problems and how to fix them.

The SA-BEST leader, whose party is aiming to hold the balance of power after the election, is featured with some Bollywood dancers and rising from a hospital bed in the two-minute video released on Tuesday

"The state is going backwards, let's stop that in its tracks. A true-blue caring party, that's what SA lacks," he sings.
